If it is worth it to you to spend the $$ to re-spray, then that is all that matters. Honestly, 99% of the time that you are inside the vehicle driving, does the color affect you, probably not. If you are truly unhappy with the color, there are vinyl shops that wrap for about $900-1200 (non matte color), or you can plasti dip the car. I feel you about the color, and understand your pain for the 3rd row need. I could never live w/o the 3rd row right now as well. If you have the money, re-spray it, and make life simple without the worries of damage to the vinyl or plasti dip.
Remember this is your rig, and you build it how you want it, even if it means re-spray, however, my advice, with the mods listed, you will have an awesome rig no matter what, and it IS a T4R, in a pretty cool color as well. Good luck with the build either way you build it!
